Rural & Urban Areas(World)

Page 77: Ecology

Rural Area is a geographic area that is located outside cities and towns.

Page 78: Ecology

Urban AreaUrban area is the region surrounding a city.

Most inhabitants of urban areas have

nonagricultural jobs. Urban areas are very

developed.

Urban area can refer to towns, cities, and

suburbs.

An urban area includes the city itself, as well as

the surrounding areas.

The Reproductive Health (RH) bill promotes information on and access to both natural and modern family planning

methods, which are medically safe and legally permissible.

It assures an enabling environment where women and couples have the freedom of informed choice on the mode of

family planning they want to adopt based on their needs, personal convictions and religious beliefs. The bill does not have any bias for or against either natural or modern family

planning. Both modes are contraceptive methods. Their common purpose is to prevent unwanted pregnancies.

It proposes that the Philippine government and the private sector will fund and undertake widespread distribution of

family planning devices such as condoms, birth control pills (BCPs) and IUDs.
